On March 13, a bureau of the State Grid completed a line channel elimination task in the Tanshifang Line channel. This task is to use a new dedicated "tree cutting laser gun" to clean up 500KV Tanshifang line 48#-49# channel in the tree group, these trees are a serious threat to power safety, and because the trunk is very thick, manual cleaning and difficult, the use of cleaning floating hanging objects dedicated laser barrier cutter cutting is almost impossible to cut, so the use of a new tree cutting laser gun remote processing, It's fast and secure.

This tree cleaning work is completed with the assistance of our company, using the newly developed 6th generation power laser cannon, specially designed for cleaning up the power channel trees, raising the traditional laser obstacle clearing instrument to the world's leading level, thus greatly improving the efficiency of tree cleaning, the task that originally took one or two hours to deal with, now only takes a few minutes, the efficiency is increased by more than 10 times. It plays an important role in better ensuring power safety. The new laser cannon used this time is the latest result of the company's technical team through years of dedicated research and development, all core components are independent research and development, with several aspects of technological innovation, the first is greatly improved portability, weight from the conventional 35Kg to only about 14Kg; The second is the use of a new high-precision self-developed head, response speed and control accuracy and load capacity increased by more than 10 times; Third, the laser spot focus is extremely fine, the power density is greatly improved, and the tree trunk of about 10cm can be broken down and vaporized almost in a moment at the place where the spot is cut.

Through the cooperation of the team members of the UHV Branch and the engineers of the Red Bank Base, the crown of 8 tall trees there was successfully cut to the safe distance of the passage. These trunks were very thick, with a diameter of 10-20cm. If the laser obstacle clearing instrument used to clean the floating hanging objects could only handle the branches of 2-3cm thick, it was impossible to complete the task of cleaning such large trunks. The elimination work is a typical successful case of the ultra-high voltage branch of State Grid Sichuan Electric Power Company using cutting-edge scientific and technological achievements to better protect power safety. Because the efficiency of the new laser gun is much faster than that of manual cleaning, it not only improves the efficiency of the operation, saves the cleaning cost, but also protects the main body of the trunk from being affected, thus protecting the ecological environment, and has high practical value and social value. As a global technology leader, the new tree cutting laser gun will shine in the future in line elimination and protection of power safety.
